Fix phy_read/write redefinition errors in ucc_geth_phy.c

The local versions of phy_read() and phy_write() in ucc_geth_phy.c conflict
with the prototypes in include/linux/phy.h, so this patch renames them,
moves them to the top of the file (while eliminating the redundant prototype),
and makes them static.
